The Remedy To A No Internet Access Ailment
There is really no definite answer for a no Internet access problem. But as with solving any problem, the best practice is to break things down in order to have an organized approach in solving it.
There are at least three possible reasons why this problem occurs: First, it could be that there is a problem with your Internet connection. Second, the problem could be in your home network devices such modems, routers or ethernet cables. And third, the problem could be in the software such as drivers or incorrect configurations within your computer system.
No Internet Connection
You should always check your Internet connection first. Who knows, maybe there is no data coming from your servicer provider. You will never know if you only have one computer in your house. If you have smartphones or tablets, they will do. If not, try to borrow your friend’s laptop or tablet, provided that you have WiFi connection in your house and not just an outdated modem with no wireless connection capabilities.
If your friend’s laptop or mobile device established a connection successfully, then the problem could be in your laptop or PC. If not, the next step is to check your modem and/or router, the way they are set up, and their cable connections.
Incorrect Setup of Home Network Devices
The most common issue regarding home networks is having two devices that are doing the same task. This happens when you already have a modem while you were using a PC. And later on, you bought a laptop and you realized that you needed to acquire a wireless router so you can have the liberty of using the laptop anywhere in your house.
So now you have two devices for your home network. If you start noticing that your Internet speed is getting slower or worse, when you look at the bottom right-hand corner of your screen and it says, “no Internet access,” then you should check your network devices. If you connected your modem to your wireless router by way of the WAN port, you are actually having two devices that are acting as the router.
What you don’t realize is that you now have two default gateways. A gateway is also known as the IP address of the router.
How does that work? If you look at your home network devices, you have a modem and a wireless router. Now, the modem actually has a router function built in; it’s just that it’s not wireless.
Basically, the function of the router is to pass data between networks. The data packets are coming from the networks outside of your house to the network inside of your house. Therefore, the modem is acting as the router and so is the wireless router.
Your Wireless Router as a “Switch”
What you need to do is to turn the router function of the wireless router “Off,” and only use the router function of the modem. What you’re also going to do is have the wireless router turned into a “switch.”
So, what is a “switch”? It is a device that gives the modem additional LAN ports. The modem only has one ethernet port and one USB port, and this means that the modem can only have two computers connected to it.
With the wireless router acting as a “switch,” you can have more computers connected to it because there are more ethernet ports and antennas for wireless function as well. This feature of a wireless router allows more computers to be connected to your home network.
So how do you turn your wireless router into a “switch”?
Remove the cable from the WAN port and instead connect it to one of the LAN ports of your wireless router. Since your modem is a router, it is the one responsible for passing information from the Internet to the computers of your home network.
Check also your cables if they could be causing the problem. Try swapping between cables to check for defective ones. Ethernet cables are not that expensive and they’re quite easy to replace.
Incorrect System Configuration
If you are able to browse the Web with your tablet and smartphone but not with your PC or laptop, then check the network settings of these devices. Try to check the time and date settings, as your browser will not run with incorrect time and date. When the Airplane Mode is turned ON, this will automatically turn your WiFi connection Off, so check this too.
Check the network adapter, its settings, its driver (if it needs an update), and if it’s functioning properly.
Are your devices free from malwares? There are different types of malwares and each has different characteristics depending on what it’s programmed for. Be sure to have a reliable antivirus software in your devices and that it’s always updated. Even if you’re always doing a safe search, you will never know that a malware has already entered your devices.
The PING Command
If the problem still goes unresolved, then it’s time to use the Ping command. This command can be used to trace the path where the breakdown in communication is happening. But first, you need to find the IP address of your router.
You have to run the IPCONFIG command at the Command Prompt to find this IP address. A standard IP address starts with the numbers 192 and other number combinations would be invalid. An invalid IP address is one of the reasons why a network fails to establish an Internet connection. This is also an indication that you have a problem with your router and the TCP/IP or Transmission Control Protocol/Internet Protocol.
When you have done everything you can but still having that no internet access woes, then probably it’s time to talk to your Internet service provider. When a signal strength goes on and off and most of the time is weak, it is an indication that you have poor Internet connection and maybe it’s about time to change your ISP.
